Chester are being forced to put some of their players on the transfer list after being told by the Football League they have breached their approved salary cap for the coming season.
The League Two side will not be able to bring in any new players until their wage bill is reduced.
Chairman Stephen Vaughan said they had already listed Lee Steele and Sean Hessey to help reduce the wage bill but added they would be holding talks with medical advisors and the Professional Footballers' Association about injured midfielder Glenn Cronin.
"We have already addressed the situation by placing Lee and Sean on the transfer list after Bobby Williamson decided they didn't feature in his future plans," Vaughan told the club's website, www.chestercityfc.net.
"However, at this present time we haven't had any firm offers for them.
"We now also have a situation with Glenn, who missed virtually all of last season with a broken metatarsal and now unfortunately has suffered a similar injury which is expected to sideline him for the majority of this campaign.
"It could well be that we have to discuss this situation with the player, medical advisors and the PFA to review the problem."
